GAS DNA CO2 Detector CD-30M/30I

Category: Gas Detector

CD-30M/30I are designed for air conditioning system being installed on air conditioning duct system. With built-in transmitter, CD-30M/30I can detect CO2 gas density using NDIR (Non Dispersive Infrared) and convert the measured density signal into linear current or voltage signal to be transmitted to external monitoring unit or controlling unit such as PLC or DDC.

[ Features ]

Non Dispersive Infrared(NDIR) CO2 sensor
highest detection accuracy and the longest sensor life time with the least affection from other gases.
Built-in transmitter
Built-in transmitter transforms the sensor signal into stable standard current output signal (4-20mA) to be transmitted to external controlling equipments such as PLC or DDC.
Robust metal housing
RS-485 enables stables stable and long distance (maximum 1.2km) signal communication.
